Improved spoke-machine



UNITED STATES PATENT OFFICE ELI K. VVISELL, OF WARREN, OHIO.

IMPROVED SPOKE-MACHINE.

Specification forming part of Let-ters Patent No. 37,839, dated March 3, 1863.

To a/ZZ whom it may concern:

Be it known that I, E. K. WISELL, of Warren, in the county of Trumbull and State of Ohio, have Amade new and useful Improvements in Spoke-Machines; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is atop view. Fig. 2 is a side view. Fig. 3 is an end view. Fig. 4 is a side view opposite that shown in Fig. 2, and Fig. 5 is an end view opposite that shown in Fig. 3.

Like letters refer to like parts in the several views.

The nature of my invention relates to cutting the spokes in longitudinal sections by means of a revolving cutter and aI traversing motion of the spoke and pattern, and the rot tion of the spoke and pattern by sections in concert with each other, as hereinafter described; to the inclined planes for feeding or giving motion to the rotating gears for the spoke and pattern 5 to the roller upon which the pattern rests 5 to the cutters in combination i with a traversing frame and spindles which carry the spoke and pattern, and to the apparatus for throwing the traverse-frame out ot' gear.

The main frame of the machine is represented by A A. Upon the back part is situated four short posts, B B B B, which support traverse-rods O G. A traverse-frame, D, articulates upon these rods and has atraversing motion upon them equal to the length of the spoke, by means hereinafter to be described. The front edge of the traversingframe is provided with two head-blocks, E E. These head-blocks carry two sets of mandrels, F F and G G. The mandrels F F support and carry the spoke-pattern, and the mandrels G G carry the bolt or timber from which the spoke is made. The mandrels F and Gr rotate upon their own axes in concertwith each other and in the same direction, by means of gearwheels H H and the intermediate gear-wheel,

H, which causes the wheels H and H to rotate in contact with each other and in the same direction. The gear H on the mandrel G is indicated by dotted lines in Fig. 5, as the wheel itself is hidden from view by the ratchetwheel I, which is secured thereto. The ratchetwheel I is operated by a pawl, l', by means of the bent lever I". At the head end of the machine are situated two inclined planes, J J', which act upon the free end of the bent lever I at every traverse of the traverse-frame D, and thus moving the ratchet-wheel I in the direction of the arrow one notch, and consequent] y both the spoke and pattern are turned on their axis a corresponding degree, so if there are thirty notches in the ratchet-wheel I and the paw-1 so adjusted that it takes one notch at each movement, it follows that the traverse-frame must move fifteen times in each direction before the spoke and pattern would make one complete revolution. This movement of the traverse-frame in each direction is nearly completed before the inclined planes J J are reached, so that the spoke and pattern are both at rest as regards rotation during most of the traverse motion, and only turn upon their axes when the lever I is ascending the inclined planes J or J f. A roller, K, is placed on the top of the frame in front of the revolving cutter and upon which the pattern rests. By this means the pattern is protected from wear by friction, for in any case the pattern -must recline upon a rest in line with the cutter in order to give the shape of the pattern to the spoke.

The revolving cutter is represented at L. This consists of a wheel with gouge-shaped cutters L on its periphery, and having a rapid motion bymeans of the drivingband L from the drivingpulley M upon the shaft M. The traverse-frame D receives its motion from the crank gear-wheel N by means of a connectingrod, N', and arm- N, which arm projects downward from the under side of the traverseframe D. The crank gear N receives its motion through the pinion O. belts O and O, from the driving-shaft M. The pulleys which carry the belts O and O are cone-pulleys, so that the motion of the traverse frame can be varied at pleasure. At every complete revolution of the sli oke-pattern, the traverse-frame is thrown out of gear for the purpose of putting in a new spokebolt by a mechanism, which I will now proceed to describe.

Upon the outer end ot` the mandrel F is aI finger, P, which rotates with the mandrel, and at every complete revolution is brought into contact with stud Q, Figs. 4 and 5. This stud is attached to the upper side ot' a sliding bar, Q', which rests upon the top of the frame just beneath the outer edge of the traversei'rame D upon that side that carries the spokepattern. To the opposite end of this sliding bar'Q' is attached a bent lever, Q", having its fulcrum at R upon the top of the-frame, as seen in Fig. 1. The long arm ot' this bent lever is attached to the tail end of the sliding bar Q', while the short arm R.' rests transversely upon the top of the end piece of the frame, as seen in Fig. l.

S represents a lever which has its fulcrum at S' on a short standard, rising from the frame of the machine. The short arm of this lever supports a sliding bar, S", which carries the box of the journal of the pinion O. The short arm ofthe lever S being pivoted to the sliding bar S", as seen in Fig. 5, it follows that it` the long arm of the lever S is depressed the pinion will be elevated and thrown out of gear with the crank wheel N. A rod, T, is 1 ivoted to the long arm of the lever S, as seen in Fig. 3, and the rod passes loosely through a mortise in the frame of the machinejust at thepoint where the short arm got thebentlever rests upon it. The rod T has a shoulder, T', which rests upon the upper surface oi the frame when the pinion 0 is in gear. To the lower end of the rod T is attached a weight,

the rod T is caused to fail by means of the ac tion of the arm R' and the pinion O is lifted out of gear, and the traverse-frame remains at rest to receive another spoke-bolt.

For the purpose of securing the traversei'rame from shoving endwise while introducing a new bolt, I attach a catch, V, to the rod T, so that when the rod T falls to lift the pinion 0 out of gear the catch takes hold of the vtraverse-frame and holds it in place, so that the revolving cutters will not strike the bolt till the pinion O is thrown again into gear by raising the rod T to the position shown in Fig. 3.

What I claim as my improvement, and de sire to secure by Letters Patent, is

1. Outtin g the spokes 'in longitudinal sections by means ot' a revolving cutter and a traversing motion of the spoke and pattern, and the rotation of the spoke and pattern by sections in concert with each other, in the manner specified.

2. The roller K upon which the pattern rests, for the purpose specified.

3. The inclined planes J J', in combination with the pawl and ratchet I l', when arranged and operating as and for the purpose speciiied.

4. The finger P and rod T, when arranged and operated as described, for throwing the traverse-frame out of gear.

5. The traverse-frame D and mandrels F F' and G G', in combination with the revolving cutters, arranged and operating as set forth.
